    Hi. I have some questions about Apple Airport Express to which I can't seem to find any answers online:

    1.) Is it a wireless router or just a wireless access point?
    (I would need a router in order to make a small wireless home network. I connect to the internet through a switch, which has no home network capabilities)

    2.) Can you run it in b/g/n mixed mode?
    (I need it to run in full speed N mode, but also connect a b/g laptop at the same time)

    3.) Does it support multicast so that I can stream IPTV wirelessly to my Macbook?

    Thanks.

    1. Yes, it is a router.
    2. Yes, it works with N devices and B/G devices concurrently (but as flopticalcube notes below, not at full speed. Forgot that! :p)
    3. Yes, any protocol that works over IP should work on an AirPort Express.

    Good luck!

    Mixed mode will not bring full speed n. The best you can do is 130mbps in mixed mode vs 300mbps in pure n.

    So if I switched to "N" only I can have faster speeds?

    Using wide channels at 5ghz you can achieve nearly 300mbps. Range will be limited, however.

    What kind of range am I looking at?

    Oh, that's ok for me - I have 100mbps internet connection anyway.



    Hmm..I can't find anything about changing the multicast rate in the manual?

    I found I could get full speed up to 20 feet in the same room. It drops down if you move to another room to about 170mbps. 2 rooms and 40 or 50 feet and you might get 130mbps. This was on my old MacBook. If you have that kind of home, an Extreme might work better.

    You're right the manual doesn't mention the multicast rate - pretty useless. There has been some previous discussion.

    Higher multicast rate = more speed, less range
    Lower multicast rate = less speed, more range
